Abstract

    Through this research, polymeric composites were prepared from epoxy as a base material with silicone rubber by adding different weight percentages of silicone rubber. After conducting the experiments, the weight ratio that recorded the highest results was selected and a heat treatment was conducted for it at different temperatures (8,25,55)ºC. Some mechanical and thermal tests were conducted for it. The results, when comparing before and after the reinforcement process for the composites, showed that the thermal conductivity decreased after the strengthening process, as for the resistance to hardness, compressibility and flexibility. The values ​​increased after strengthening, but the value of hardness, compressibility and flexibility was less at (55) C compared to the results at (8) C. As for the shock resistance, its value increased after strengthening and the increase was greater at (55) temperature compared to its value at (8) C.
